Hi Friends,

Recently I had configured sendmail in my linux centos version 6.
All is working fine. But when I send mail to gmail and hotmail its goes to spam folder. Even I added SPF record But still I am getting same problem. I had installed spamassassign and clamav but nothing happened.The following is the one of my test Email Header

Hi

This message has been scanned for viruses and
dangerous content by MailScanner, and is
believed to be clean.

I am tried last 3 days. But No use. Please help me on this issue. I am using sendmail version 8.14

Thank you

Assuming you're not actually using "admin@example.com" as your e-mail address address (which would be considered a forged "from" address and will cause your mails to be classified as spam), it seems there's something wrong with your SPF records:
Your server obviously has both an IPv4 and an IPv6 address (good!), so make sure to create both an A and an AAAA record.

You may need to set up a reverse DNS record so that it's more likely that your email won't get wrongly rejected as spam. Also, consider setting up SenderID and DKIM.

Thank you for the reply.

This is my SPF record:

v=spf1 ip4:172.13.4.9 mx a:www.example.com mx:mail.example.com ~all

Reverse DNS we already configured.
Thanks

Thanks for the reply,

Sorry I cant understood, Please can you explain little bit.

Thanks

The SPF error indicates that the receiving mail server fails to find an IPv6 record. You should add "ip6:2a00:1a48:7805:112:2731:a0d9:ff08:4b1a" to your existing SPF record.

You may also want to add an IPv6 AAAA record for your mail server.

Ser Olmy, you may want to read some of saran_redhat's previous posts:
http://www.linuxquestions.org/questi...em-4175462017/
http://www.linuxquestions.org/questi...nx-4175462185/

...where they've been asked questions specifically about why they're pretending to be Wells Fargo Bank from the US, and doing website redirections to Nigeria (home of the 419 scam).

Saran_redhat, do you have any answers for the questions you've been asked before?? This seems like a continuation of some of your previous threads...and based on your avoidance of the questions before, it would lead someone to assume that you've modified the email headers posted, to be "admin@example.com", rather than what you previously posted:
Did you ever reply to the moderators direct email about this? Because you certainly didn't respond in the threads you posted. Personally, I will be more than happy to help you if you have reasons for such things, but I really will NOT help spammers/scammers shovel out more emails.

saran_redhat, can you please tell us the answers?
